摘要
对锌焙砂硫酸浸出渣中铁酸锌进行分离提纯,得到铁酸锌含量达98%,晶体结构中含硅、铝、锑等微量杂质元素的产品1对其进行机械活化处理得相关系数为0.999943时的多点BET比表面积为2.8249 m2/g,单点平均孔半径为15.66 nm,0.448~1.002μm和1.002~10.024μm粒级范围内粒度分布分别为27.93%和53.48%的产品2对比纯铁酸锌、产品1及产品2同条件下对罗丹明B的处理效果,结果表明经机械活化铁酸锌粉体对罗丹明B吸附能力较强。微波功率低于500 W时,吸附-解吸过程受功率大小影响较大,微波功率大于500 W时,微波催化降解作用较明显。
In this paper, simulating industrial leaching process of zinc calcine and refine zinc ferrite from slag. Prod- uct 1 contains 98% zinc ferrite and silicon, aluminum,antimony and other trace impurity elements in crystal struc- ture. After mechanical activation got product 2 has muhipoint BET specific surface area is 2. 8249 h/g, the average pore radius of single point is 15.66nm, and graded size distribute within the scope of 0. 448 - 1. 002 um and 1. 002 - 10. 024 urn are 27.93% and 53.48% respectively with correlation coefficient is 0. 999943. Compared treatment effect of pure zinc ferrite, product 1 and 2 to rhodamine B under the same condition, the results show that the ad- sorption capability for rhodamine B of ferrite zinc powder body stronger after mechanical activation. Adsorption-de- sorption process is greatly influenced by microwave power when it is less than 500 w, and degradation effect of mi- crowave catalytic more apparent when power above 500 w.
